TinyPICO: The mighty ESP32 development board that's smaller than a thumb
If you ever wanted an ESP32 development board that was even smaller than an AA battery then you might want to take a closer look at the TinyPICO. Although this board only measures 18 mm x 32 mm the developer, Unexpected Maker, has managed to jam-pack it with features. The TinyPICO has a 32-bit dual-core processor that operates at 240 MHz, and there is 4 MB SPI flash and 4 MB extra PSRAM.
Along with wielding incredible processing power for such a minute board, the TinyPICO offers full Internet connectivity with 2.4 GHz Wi-Fi (802.11b/g/n) onboard. Along with the chip from Espressif Systems and the ability to get online, the small development board also has red and orange LEDs (for power and charge) and includes a 700 mA 3.3 V regulator.
On top of that, the TinyPICO has a variety of shields available for it. There’s a Play Shield with a 128x64 white OLED for those who want to try some gaming with the diminutive board and there’s an Audio Shield that includes a magnetic buzzer and a 1.5 W mono amplifier. A single pledge of US$26 secures one of these boards, which come with MicroPython software preinstalled. Orders are expected to start shipping on July 25.
